Gastric acid secretion is regulated by hormones in the digestive system. This hormone, gastrin is secreted by the lining of the stomach.
It is a hormone produced by stomach.Itg stimulates secretion of gastric juice.
The component of gastric juice that acts as a hormone to stimulate gastric secretion and movement is gastrin. Released by G cells in the stomach lining, gastrin promotes the secretion of gastric acid (hydrochloric acid) from parietal cells and enhances gastric motility, facilitating digestion. Its release is triggered by the presence of food in the stomach, particularly proteins.
HCl (gastric acid), pepsinogen.
Gastric Acid
ANSWER IS: Gastric secretion can be stimulated before food has entered the mouth.A.Gastric secretion can be stimulated before food has entered the mouth.B.Gastric secretion is enhanced by very low pH (below a pH of 2)C.The presence of food in the stomach prevents hormonal control of gastric secretion.D.Vagus stimulation of the stomach results in decreased secretion of gastric juice.
B. Inhibit gastric secretion. When food enters the small intestine, signals are sent to the stomach to reduce the secretion of gastric juices to prevent excessive acid production and aid in the digestion process.
Hormones that inhibit gastric secretion include secretin. It is a type of hormone that is released into the bloodstream by the duodenum.
enterogastric
Sympathetic activity inhibits gastric secretion by causing vasoconstriction of blood vessels in the stomach lining. Parasympathetic activity stimulates gastric secretion by increasing blood flow and activating gastric glands, leading to increased production of stomach acid and digestive enzymes.
The parasympathetic is stimulatory to stomach , increase the gastric secretion and motility while the sympathetic is inhibitory , decrease the gastric secretion and motility
gastrin
Gastrin is a hormone secreted by the stomach which stimulates the secretion of hydrochloric acid, increase motility, and stomach emptying.
